Structure Two Sugar Di saccharide
Structure One Sugar Monosaccharide
Function n Provide QUICK energy to the body!
Bellchallenge : Loaf of bread Monosaccharide Explain what you think is happening here. (at least 3 sentences) Bread crumbs Polysaccharide Disaccharide The diagram shows a picture of bread (starch). It also maps out the break down of carbohydrates from their most complex form (polysaccharide) to their least complex (monosaccharide). This process is called

Breaks down into microscopic molecules Fats, oils, waxes, steroids
Monomer: 3 fatty acids + glycerol
Polar head (&hormones) Non-Polar head Phospholipids & steroids join together w/proteins in the cell membrane
Function n Made mainly of carbon and hydrogen (few oxygen) n Fat best method of STORING n forms cell membranes n Insulates nerve cells (myelin) n Insulates body (maintains homeostasis)
How are complex carbohydrates formed and broken down?
Dehydration Synthesis n Combining single compounds into a complex one by removing water monosaccharide + monosaccharide ----> disaccharide + water C 6 H 12 O 6 + C 6 H 12 O 6 ----> C 12 H 22 O 11 + H 2 O (Process forms disaccharides & polysaccharides)
Hydrolysis n Addition of WATER to a compound SPLITS it disaccharide + H 2 O ---> monosaccharide + monosaccharide C 12 H 22 O 11 + H 2 O ---> C 6 H 12 O 6 + C 6 H 12 O 6

Bellchallenge: Describe what you see (at least 3 sentences) This is an amino acid. It is the monomer for a protein. It contains C, H, O and N. It has 3 groups: an amino group, an R-group, and a carboxyl group. The R-group is considered a variant group because it
Friday 9/17/10 Agenda 1. Proteins 2. Test for Organic Substances (Parts C, D &E) 3. Complete analysis questions 4. HW: Venn Diagramcarbohydrates, lipids, proteins
Proteins aka…. Whey Protein Meat Polypeptide Peanut butter
Breaks down into microscopic molecules Polypeptide Meat Amino Acid Monomer: amino acid Polymer: polypeptide
Monomer: Amino Acids • Contains C, H, O, N • 20 types • Has both hydrophobic & hydrophylic ends • Differ in R-group • R-group can be acidic, basic or neutral • Makes polypeptide then makes proteins
Polymer: Polypeptide (peptide means bond) • Formed by dehydration synthesis • Sequence determined by DNA • 3 -D and folds to take up less space
Function of Proteins n Provides us with building blocks for life! n Also regulate most functions in a cell. n Glycoproteins (antigens) n Combines w/DNA to form chromosomes n Turns genes on and off n Antibodies (fights disease)
Function of Proteins n Provides structure & strength (fibers) n Transports out cells molecules in & n Hemoglobin O 2) (transports n Enzymes (speeds up rxns) - has –ase suffix n Acts as hormones (insulin) - many proteins have suffix of -in
Bellringer: Describe in detail what you see in the diagram. (minimum 3 sentences) This is a picture of ATP is one type of polymer of a nucleic acid. It is made of adenine, sugar, and 3 phosphate groups.
Monday 9/20/10 Agenda 1. Nucleic Acids 2. Finish. Test for Organic Substances (Parts C, D &E) 3. Complete analysis questions 4. HW due Friday: Venn Diagram- carbohydrates, lipids, proteins & nucleic acids
Nucleic Acids n Contains C, H, O, N, P n Monomer: NUCLEOTIDES n Nucleotides consist of 3 parts: 1. 5 -Carbon Sugar 2. Phosphate Group 3. Nitrogenous Base
Nucleotide: Nitrogen Bases In DNA: C-G A-T In RNA: C-G A-U n 5 types n Cytosine n Guanine n Adenine n Thymine (in DNA only) n Uracil (in RNA only) n Purines or pyrimidines

Which biomolecule has the most energy!?
C-H bonds n Count the number of C-H bonds in your monosaccharide picture. n Count the number of C-H bonds in your saturated or unsaturated bond picture n Which biomolecule (carbs or fats) have more C-H bonds?
The number of C-H bonds = the amount of energy n. The more C-H bonds a biomolecule has, the more energy it has! n. Fats have the most energy because they have the most CH bonds!
